sv_allowupload only seems to affect cheer files, which most people don't know how to use. Perhaps it's changed recently, but the only way I've found is to set net_maxfilesize to 0. Clients will still attempt to upload stuff, but the server won't do anything with it and won't send out the sprays to other players. You'll have to delete all the .dat files in your mod's downloads folder on the client-side to get rid of old cached sprays though.
You should also note that setting net_maxfilesize to 0 also means the server won't send out any map-related downloads directly, so if you decide to use that and have map downloading, you'll have to set up HTTP downloads. _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds
